Is SACC Disclosure Required for Portable Air Conditioners?
Yes — the DOE's test-procedure final rule established SACC testing for portable air conditioners, with compliance applying starting the 2019 model year, and SACC disclosure is expected alongside the ASHRAE figure. In practice, when we compiled the SACC Reality Index, we still found budget and newer-import listings that show only an unlabeled BTU number with no SACC figure anywhere on the page.
The one thing to know: Since compliance began in the 2019 model year under the DOE's test procedure final rule, portable air conditioner packaging and major retail listings are required to state the SACC rating alongside (not instead of) the older ASHRAE rating. In practice we still find budget listings, especially from newer or smaller import brands, that state only an unlabeled BTU number with no SACC figure anywhere on the page — the non-disclosure itself is a signal worth noting, not proof of anything defective about the unit.
The rule, in brief
The DOE issued a test-procedure final rule for portable air conditioners establishing the SACC methodology, and compliance with SACC-based rating and labeling applies starting the 2019 model year. This built on the same DOE rulemaking process that established energy-conservation standards for the category, formalized in a related DOE final rule addressing portable AC energy conservation standards.
What we actually found on current listings
Reviewing manufacturer pages and major retailer listings for the models in our SACC Reality Index, most well-known brands (Midea, Whynter, TURBRO, Honeywell, LG, BLACK+DECKER) disclosed a SACC figure clearly, often directly in the product title. One budget listing we reviewed (a COSTWAY 8,000 BTU unit) showed only an unlabeled BTU figure with no SACC number anywhere on the page — we recorded that as "Not disclosed" rather than estimating a number.
Why the inconsistency exists
The underlying DOE test-procedure requirement applies to manufacturers, but retailer listing pages (particularly third-party marketplace listings) aren't always policed with the same rigor as a manufacturer's own product page or box label. A missing SACC figure on a listing is a disclosure gap on that page — it is not proof the manufacturer never tested the unit to the SACC standard, and it is not evidence the unit is defective.

Frequently Asked Questions
Yes. The DOE's test-procedure final rule established the SACC test for portable air conditioners, with compliance applying starting the 2019 model year, and FTC EnergyGuide-related labeling conventions require SACC to be disclosed alongside the ASHRAE figure.
No -- in our research for the SACC Reality Index, most current major-brand listings did disclose SACC clearly (often in the title), but some budget and newer-import listings showed only an unlabeled BTU figure with no SACC number anywhere on the page.
Treat the advertised BTU figure and any square-footage claim with more skepticism, check the manufacturer's own site for a spec sheet, and consider sizing down from whatever room coverage is claimed. Non-disclosure on a single retailer listing isn't proof the unit underperforms, but it does mean you can't make the SACC-based comparison from that listing alone.
The Department of Energy sets and enforces the underlying test procedure and reporting requirements for manufacturers; retailer listing pages are not always policed for full compliance with the same rigor, which is likely why disclosure is inconsistent across storefronts even for well-known models.
